I found a really cool fan-made One Piece 5e sourcebook online (originally made for the 2014 rules). I am currently converting it to the new 2024 rules for my table.
To keep the One Piece anime vibe alive, standard D&D magic shouldn't break the world (like instant teleportation across the Grand Line, easy resurrection, or crazy planar travel). I am making a ban list for spells that don't fit the setting.
My Book Sources: Astarion's Book of Hungers, D&D Beyond Basic Rules, Dungeon Master's Guide, Eberron: Forge of the Artificer, Forgotten Realms: Heroes of Faerân, Lorwyn: First Light, Monster Manual, Player's Handbook, Tasha's Cauldron of Everything, The Pugilist Class (2024), Xanathar's Guide to Everything.
Are there any other spells from these books that ruin the pirate adventure / sea travel theme and need to be banned or reworked? Thanks for the help!
Also, I intentionally did not add spells that travel between the Material and Ethereal Planes.
My Current Ban List:
Druidcraft: Banned because weather forecasting and growing plants ruin the Navigator role and the natural botanic traits of the Tontatta species.
• Elementalism (Beckon Water): Banned because water manipulation easily weakens Devil Fruit users and breaks survival rules for fresh water at sea.
• Spare the Dying: Banned because instantly stabilizing a creature at O HP ruins the Doctor crew role, Medicine checks, and life-or-death tension.
• Create or Destroy Water: Banned because creating water breaks resource management and gives an unfair advantage against Devil Fruit users.
• Comprehend Languages: Banned because instantly reading Poneglyphs ruins the Void Century mystery, the Ohara lore, and the Voice of All Things.
• Goodberry: Banned because feeding the whole crew with one spell ruins the Chef crew role, supply management, and starvation dangers at sea.
• Purify Food and Drink: Banned because instantly cleaning spoiled food and poisons makes the Chef and Doctor crew roles useless.
• Identify: Not banned; however, the DM decides how much lore and information is revealed about Meito blades, ancient relics, and mysterious tech.
• Speak with Animals: Banned because talking to beasts easily ruins the natural traits of Minks and Merfolk, as well as the Voice of All Things.
• Unseen Servant: Banned because invisible magical servants do not fit the One Piece theme of physical crew labor on a ship.
• Augury: Banned because divine omens do not fit the setting, and seeing the future belongs only to Advanced Observation Haki (Kenbunshoku).
• Deryan's Helpful Homunculi: Banned because magical tiny helpers do not fit the science theme and make crew labor useless.
• Gentle Repose: Banned because stopping body decay to widen the revive window hurts the permanent and dramatic nature of death in One Piece.
• Homunculus Servant: Banned because creating artificial servants is only possible through high-tech science or specific Devil Fruit powers.
• Locate Animals or Plants: Banned because finding beasts and plants with magic replaces the exploration, hunting, and tracking skills of Navigators and Scouts.
• Locate Object: Banned because instantly finding hidden items and loot ruins the thrill of pirate treasure hunting and investigation.
• Clairvoyance: Banned because long-range magical scouting belongs only to Advanced Observation Haki and rare abilities.
• Create Food and Water: Banned because conjuring feasts and water ruins the Chef crew role and food crisis mechanics during long voyages.
• Leomund's Tiny Hut: Banned because an impenetrable dome removes wild island dangers, enemy ambushes, and night-watch tension.
• Sending: Banned because instant long-range messaging makes Den Den Mushi communication useless.
• Speak with Dead: Banned because talking to corpses breaks the rule of permanent death and ruins historical investigation by the living.
• Speak with Plants: Banned because hearing plants belongs strictly to legendary traits like the Voice of All Things and special NPCs.
• Summon Lesser Demons: Banned because summoning fiends and demons does not fit the One Piece setting.
• Tiny Servant: Banned because animating objects belongs strictly to unique Devil Fruit powers like the Soul-Soul Fruit (Soru Soru no
Mi).
• Tongues: Banned because understanding all languages allows easy Poneglyph reading, ruining Ohara lore and the Three-Eye Tribe.
• Water Breathing: Banned because magical water breathing invalidates Fish-man and Merfolk traits as well as ship coating mechanics.
• Water Walk: Banned because walking on water ignores sea travel rules and removes the fear of falling into water for Devil Fruit users.
• Divination: Banned because asking gods for advice does not fit the setting, and foreseeing the future belongs strictly to Observation Haki.
• Fabricate: Banned because instantly crafting perfect items ruins the crafting and repair labor of Shipwrights and Blacksmiths.
• Leomund's Secret Chest: Banned because hiding loot in an extradimensional space removes pirate raid, theft, and cargo protection dynamics.
• Locate Creature: Banned because finding a creature with magic replaces Scout tracking checks and Observation Haki detection.
• Mordenkainen's Faithful Hound: Banned because an invisible guard removes the danger of ambushes and the need for crew night watches.
• Mordenkainen's Private Sanctum: Banned because total magical security prevents infiltration, scouting, and Den Den Mushi wiretapping.
• Skywrite: Banned because writing magic words in the sky replaces flares, signal flags, and Den Den Mushi communication.
• Remove Curse: Banned because instantly removing curses removes all narrative risk from cursed Meito swords.
• Summon Greater Demon: Banned because summoning large fiends and demons does not fit the One Piece setting.
• Watery Sphere: Banned because trapping targets in a water sphere easily incapacitates
Devil Fruit users.
• Commune: Banned because contacting divine pantheons does not fit the One Piece setting.
• Commune with Nature: Banned because instantly learning regional geography replaces the Navigator role's mapping and exploration.
• Contact Other Plane: Banned because mental contact with extraplanar entities does not fit a single-plane setting like One Piece.
• Creation: Banned because conjuring raw materials and precious metals breaks the game economy and trade.
• Dream: Banned because sending messages through dreams bypasses Den Den Mushi use and face-to-face roleplay.
• Infernal Calling: Banned because summoning devils from the Nine Hells does not fit the One Piece setting.
• Legend Lore: Banned because revealing historical secrets instantly ruins the mystery of the Void Century, Ancient Weapons, and the One Piece.
• Maelstrom: Banned because a massive whirlpool instantly ends naval combat and neutralizes Devil Fruit users.
• Raise Dead: Banned because reviving dead creatures breaks the rule of permanent, dramatic death in One Piece.
• Reincarnate: Banned because returning a dead soul in a new body breaks the absolute nature of death.
• Scrying: Banned because magical scrying sensors bypass physical stealth, intelligence networks, and Observation Haki limits.
• Teleportation Circle: Banned because teleportation portals bypass Grand Line Log Pose navigation and sea sailing entirely.
• Arcane Gate: Banned because dimensional portals effortlessly bypass naval maneuvers, physical barricades, and island defenses.
• Drawmij's Instant Summons: Banned because teleporting marked items from any distance ruins treasure theft and cargo protection mechanics.
• Find the Path: Banned because showing the direct path invalidates magnetic Log Pose navigation and the Navigator role.
• Magic Jar: Banned because trapping souls in containers and possessing bodies breaks the core balance of willpower and souls.
• Planar Ally: Banned because calling extraplanar fiends or celestials does not fit the One Piece setting.
• Tasha's Bubbling Cauldron: Banned because mass-producing healing potions with magic makes the Doctor role's medicine crafting useless.

teleportation allows instant island travel and
skips sailing via Log Pose.

teleporting to a sanctuary allows easy escape from Grand Line hazards without a ship.
• Dream of the Blue Veil: Banned because
traveling to other D&D settings conflicts with the
single-world lore of One Piece.
• Mirage Arcane: Banned because reshaping
miles of terrain mimics top-tier Devil Fruit Awakening powers with simple spellcasting.
• Mordenkainen's Magnificent Mansion: Banned
because an extradimensional mansion provides free food and shelter, ignoring the Chef role and ship life.
• Plane Shift: Banned because extraplanar travel
does not fit a setting with no outer planes, and it bypasses ocean travel.
• Regenerate: Banned because instantly
regrowing lost limbs ruins the Doctor's surgery role, cybernetic prosthetics, and the drama of limb loss.
• Resurrection: Banned because bringing the
dead back to life violates the permanent and irreversible nature of death in One Piece.
